Why not changing the project name, because of there are spaces in the name ? I try to avoid spaces at all cost, this I learned from too many lessons. You can use spaces in the AppStore title. Never tried: What happens if you use the project name with spaces (is that even possible) ? Maybe its a character issue in iOS: https://stackoverflow.com/questions/46337691/bundle-display-name-missing-space-characters How is this noted in the " "Info.Plist" file, maybe you can find some hints there ?

http://docwiki.embarcadero.com/RADStudio/Rio/en/Provisioning_an_iOS_Application Not sure if I understnad you right, but this is the desired behavior. The name of the Project (ModuleName) is taken usually as name, no need to make other changes Or are you talking about the AppStore, where you can set a app-name freely (more or less).

Use a virtual machine.

Hi there, I just stumbled about some class helpers, I rarely use, and I found that Embarcadero seems to have a different understanding of howto use them. For example TByteHelper.Parse I would have expect to use it like this: var LByte : Byte; begin LByte.Parse( AString ); // Use LByte end; Unfortunately Delphi has set Parse as static class function in the record helper, which leads to the following useage: var LByte : Byte; begin LByte := Byte.Parse( AString ); // Need an assignment here end; Why not using the first version ? I assume this if because Delphis internal types, like Byte, Integer, etc. are special datatypes, and lack a kind of "Self" behaviour. What I'm thinking of is, does the 2nd version maybe has some other advantages over the 1st version, which would make it the preferred choice. If anybody has a good reason why I should prefer the 2nd version also with my normal types and classes, please let me know.

Hello there, I was making some experiments with shrinking larger VmWare Fusion VM images, which is not as simple as it should. My configuration is: Macos Host: Mojave, VmWare 11.5.0 Macos Guest: Catalina I have found the following process to shrink the OS disk, which looks as if it works well so far. The disk-sace is free and reduced and the VM is accessible. Unfortunately the last step, to shrink the VM image itself from the host seems to be the issue now. The "pre-occupy disk space" checkbos is NOT checked, so it should be a sparse file. There is the "vmware-vdiskmanager" tool, which should be able to do this, and it comes back with "Shrink: 100% done.". It seems that after this the VM size is still original, and the VM disk is not accessible any more. Does anybody has a good tip what may go wrong here ?

@Ondrej Kelle Thanks, but I'm on Macos host and Macos guest in the VM. On Windows this task seems to be easier, but I think the real issue lays in VmWare images, which need to be resized. If VmWare itself doesn't support them, maybe some 3rd party may exists.

Thanks for the info. I thought about script on MAcos, like I have read some notes that this also supports "wipe" all unused bytes. Since I tried shrinking only via VmWare Fusion yet, on my Macos host, maybe its a good point to check with VmWare Spere, what this can offer. This seems not an easy task at all, fortunately the vmdsk images are exchangeable between Fusion, Workstation and Sphere (hope so). However, if this adventure turns out to get that difficult, I could create a new, empty VM from scratch, as usual. Only that the smallest disk size I can create via VmWare Fusion seems to be 40 GB (~30-35GB physical), while a really cleaned up VM (removed all garbage) maybe only would need only 20-25GB (I would assume).

Yes, I agree too all whats said. Still I don't like the usage of class functions on basic types, my fault

Ok, that is a workaround. But I hope that there is a better way ... Apple strikes back on iOS13 again ... I'm just still fixing other similar issues.

http://docwiki.embarcadero.com/RADStudio/Rio/en/Creating_an_iOS_App Check "using custom fonts"

Why not work and improve ? There were times when also VCL was fragile and slow.

Interesting, do you have a script which you used for that ? When I check my partitions and volums, it looks pretty clear whare the "free space" is. The problem is that VmWare seems not to offer a shrinking option for Macos, maybe only with some tweaks deep in the VmWare tools ? Since the drive images are only files, I think this should be possible somehow, maybe in best case by just editing a HEX variable encoding the physical size, and trunkating somehow. Because the partitions looks fine, only the physical size didn't change, which makes sense in the physical world.

Looking for a solution too, since I used same code as yours. Seems that SetStatusBar was deprecated, and now in iOS 13 its probably gone. https://stackoverflow.com/questions/7030682/ios-iphone-ipad-sdk-alternative-for-uiapplication-sharedapplication-setst https://developer.apple.com/documentation/uikit/uiapplication/1623026-statusbarorientation

Ok, from time to time I use records as simple parameter containers, without such convenience methods like Parse() since I don't need them (I thought I'm a little old.fashioned then) procedure TForm1.UseMyRecord(const ARec: TMyRecordTest); begin ARec.Parse( '42' ); // This opens a "backdoor" to the const record, better don't do if ARec.FField = 42 then begin ARec.FField := 0; // This doesn't compile, thats fine end; end; Thats enough reason for me to start liking ugly constructions like LMyVar := Byte.Parse('42') ;

Aha, right. Thats a good reason to use the 2nd version. I thought that I would get a warning, that I cannot modify const. Have to check how this behaves ...

Nice visualization. Like always with such statistical data one should ask where does this come from ? How does GitHub evaluate "popularity" ? Isn't "popularity" just high because you can do small tasks easily ? Maybe such popularity index must be weighted against the complexity of projects as well. This also gives a clue to what developers maybe really like, as its seems to be a kind of simplifications in the language itself (JS amd Python). Anyhow, I don't really agree on this, as typed languages has a much practical benefits. Easy-to-learn is maybe not the only core feature of popular languages. From my experience, the languages are more or less irrelevant, but the libraries and frameworks do. I like all C languages, because they are "readable" for me, as C++ developer, although there are still many different features in each of them. Aren't JS/Python not only that popular because of their fantastic libraries and frameworks out there ? For me the key benefit of a language is not to support all small features like Nullable or Inline variables (nice to have, but not mission critical), but most important for me are stable and effective frameworks (VCL/FMX), encapsulating the complexity of the real world underneath. Regarding Delphi I would like to ask: Why can't I use ALL the core libraries of the modern OS, like beacons, sensors, ARKit, etc. etc. at 100% yet ? If so, there would be no need to move to Swift, JS or C#, only because I need to solve a special task, unreachable from FMX right now. Same for VCL and WinRT, but the situation is much more relaxed there, from the history of Delphi. Maybe I'm wrong, and there are different opinions for sure, but I would put most efford on building infrastructure and quality around libraries, instead of trying to follow the last hype in language theory. The "ease-of-use" is not by leaning only 20 keywords instead of 40, but to be able to use powerful libraries that encapsule all OS features in a nicely, cross-platform way, which are easy to learn, self-explaining, consistent, powerful and error-free. Furthermore to have powerful debugging tools as well, around this infrastructure.

Still no luck, but I added the step fragmentation before the shrinking. After the shrinking, I've got missing user access, so I solved this by giving access to everyone again: --> sudo chmod -v 666 /Users/myusername/Documents/Virtuelle\ Maschinen/macOS\ 10.14.7_Rx1032B_2_BETA.vmwarevm/Virtuelle\ Festplatte.vmdk After that the VM is running again, but still the physical size is not shrinked, although the internal partition is shrinked as it should. Maybe somebody has a clue how the VM image could be shrinked physically as well, maybe there are some tools out there (Paragon, etc.), but I could find any tool yet solving such specific issues with VmWare Fusion images. I nobody has some clue, maybe I have to restart again with some older, clean images, but I would like to know howto cleanup existing images for the future. What I cannot believe is that a modern file system like AFPS and VmWare are not able to allow a simple shrink of the file, only with a lot of terminal command steps, as below. Isn't this the 21st century now

I've just tried my proposal on a Mojave VM, which I updated to Catalina. 1. With old Mojave Mac: Copy and backup ApplicationLoader from the OLD installed XCode package. Right click at XCode and select Show package content 2. Get he AplicationLoader app from here 3. Application loader is an self-containing app 4. Compress the app to ZIP file (this I needed to do, because I had issues to copy the .app onto my server) (Maybe this is again some strange security issue of big A) 5. I could copy the ApplicationLoader locally w/o problems, e.g. to the Macos desktop. 6. Upgrade Mojave and install Catalina (I removed and cleaned up XCode completely, except my copy of ApplicationLoader of coarse),. 7. Now I have Catalina, and I can start ApplicationLoader from old XCode. All seems to work nice and smooth, I didn't made a real upload yet, but I uploaded an old app and got the usual messages, after checking with iTunesConnect. Seems to work fine, probably still OK for a while ( Catalinas lifetime ??).

I like the growing support for C++, maybe one day I have the chance to migrate my projects back to C++ if its stable enough. The whole advantage of C++ would be if all these countless popular C/C++ projects like ImageMagick, OpenCV, LibVLC, etc. could be build from CppBuilder out-of-the-box, has anyone tried yet ? As I understood David Millington, Embarcadero has seen this big advantage as well, and is working in that direction to bring C++ world more close to Delphi.

Nice, thanks for the link. Is'nt this as well deprecated together with ApplicationLoader ? @Jose Morango Since ApplicationLoader is only an app, maybe its possible to extract this from the old package before updating to XCode 11. Probably this only uses such the commandline tools. So then this could work for a while, until Embarcadero solved the topic, and there would be no need to install the whole XCode10 package. Have you checked if this might be working and what dependencies you need for ApplicationLoader ?

@Alexander Sviridenkov I use and like your library, although I must say this is sometimes not easy to figure out how simple, obvious tasks are intended to operate in runtime and designtime. Please provide more of such samples, to get clear about the intended use and possibilities.

I use JSON field for a similar approach, but I need to have saved the current state of a table document as safety backup. Since table entries might change over time, and building a history-safe table structure is somewhat brittle, I decided to store a copy of the current document (with main table entries) as JSON backup. No matter how the database structure and the data might change over time, I have valid backups when I release a document. So that I can surely find the state that is related to a special ID and date. Works fine, but of coarse there is the lack of search, but since the current tables refer to the momentary situation, I do not need to search in JSON really, Only when I need to restore old settings, I simply readout the JSON, and there is may be different versions of parameters stored in the JSON over time, which I can manually adjust if needed. Not sure if it is a good idea to have such field as main operating field, I guess this has too many drawbacks (speed, no seach, not easy to isolate between multiple user edits, etc.). Especially as you wrote that these fields need to be changed frequently. But if the field is just an addon to the normal table structure for a special use, as it is in my case, this might work fine. Maybe a clever mix of DB table fields and JSON fields can keep best of both worlds, but this highly depends on your project.

Good point. I didn't count the many times when extracting from fast demo code with nested methods to private methods. Maybe this is the kind of "Evolution" how code might evolve over time, in the process of testing different approaches for a solution.
