Using a prior iOS or macOS SDK with Delphi

[Rollo62 536]

@Dave Nottage

Hi Dave,

 

thanks for your nice article about a major problem in the Apple environment.
Yes, Apple always keeps us busy with such unnecessary work.

 

Since I had fallen into such nasty boobie trap in some older version before, I changed my way howto deal with these updates.

So I may provide another (pseudo)-solution to this topic:

Solution 3: ( prerequisites before starting any update )

• Use your XCode environment for development in a VM virtual machine, like VmWare Fusion
• Make a backup of your VM image, BEFORE any update of the VM
  (if you prefer snapshots, thats fine too, if you cleanup later, but I prefer to make complete, FULL clones of the whole VM)
• In the VM backup also the current SDK's are backed up of course, if you ever need them again later
• With these FULL clones you can switch fast and easy between older and newer XCode, SDK and PAServer setups

 

That doesn't solve the basic problem, of course,

but makes it much easier to handle different SDK environments, in case of any "crash" might happen wit the new version.

Maybe somewhat related to this, I just fell (again) into the other Apple trap.

 

By leaving aside the working XCode VM, only for some days/weeks, to test and prepare Android.

 

Today I try moving back to the current system (same VM, same XCode, sam OS 10.15.5, same iPhone (13.5), etc.

The iPhone is suddenly no more detected by XCode, even that iPhone is connected to the VM and listed in the USB.

(usualy restart, reboot OS and Phone already done).

 

 

I had similar cases before, where current, working setups ( of the former versions ),

suddenly disappear to function with XCode and RadStudio.

And yes, IT IS NOT A DELPHI ISSUE.

The general recommendation to this is, to update to the latest versions (at least thats what Apple says ).

If I do that, then I'm back to entry 1. of this thread, and the new versions cause other issues.

 

So at the moment I try to install the new OS 10.15.6 only, with the hope that this might be sufficient to detect iPhone again.

 

This is typical Apple, to me it looks like a modern way of planned obsolescense, which is absolutely annoying.

I only can say, if I wouldn't have to provide iOS solutions, I would recommend to everybody to stay away from Apple purchases.

Usually I'm quite neutral, but Apple already costs me days of my lifetime, for their daily nonsenses.

 

Go and better buy Android products

Nope: An update to Macos 10.15.6 doesn't solve it.

So maybe I'm foreced to update XCode and/or iOS too, but I try to keep it at the moment,

maybe there is another idea howto make XCode detecting my phone again.

 

Updating iOS to 13.6 will also break my XCode connection, and I cannot debug SDK 13.5 there.

@Dave Nottage

Regarding the iOS13.6 SDK, with XCode 11.6, I'm not sure what is missing there.

I just checked the XCode package content, looks like this, seems OK to me at first sight

 

The /System folder is not "empty", but I have not checked out the SDK in my projects yet.

As per the article: "The /usr/lib/system folder underneath simply does not exist"

[Rollo62 536]

So could you fix it ?

I just made a normal XCode update to SDK13.6, did you do this update via command line ?

 

Have you checked if XCode is veryfied ?

Like that, or

 

Quote

/usr/bin/xcodebuild -version

Quote

E.g.

cd /Applications
xattr -d com.apple.quarantine Xcode.app

or

 

Verifies that the Xcode installation is properly signed by Apple

fastlane run verify_xcode

My Xcode was updated to 11.6 via the App Store app on my Mac. It includes the iOS 13.6 SDK.

fastlane verified Xcode as OK.

Not as yet

[Rollo62 536]

Strange, I think I did the same here in my VM.
But as you know I have other issues, VM cannot find my devices anymore, only a real Mac on XCode 11.6 can still do.

I assume you did already XCode cleanup complete and reinstall.

 

Edit:

Something like this

or that.

@Dave Nottage

Maybe this is a hint

Quote

Remove the files at ~/Library/Caches/com.apple.dt.Xcode is basically clearing the cache.

You can delete anything under /Library/Developer/ directory, such as CommandLineTools and CoreSimulator,

 

except PrivateFrameworks subfolder.
This might cause your newly installed Xcode to crash until you put it back.

Are you saying that the /usr/lib/system folder exists in your iOS 13.6 SDK? i.e. the full path:

 

  /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneIS.platform/Developer/SDKs/iPhoneOS.sdk/usr/lib/system

No, I did a normal upgrade. Why would I need to completely uninstall?

[Rollo62 536]

@Dave Nottage

Yes, I've took that picture from Finder, in the post above.

It exists in the iPhoneOS.sdk path, as well as in the iPhoneOS13.6.sdk path.

Also I did a normal update via AppStore, to get that picture incl. /System.

But maybe in case of somethings wrong, I considered a full clean, I did some times before.

Was not necessary this time.

The picture does not show the folder that I am asking about. Please read my answers carefully.

[Rollo62 536]

@Dave Nottage

Sorry, I've tried do read as carefully as possible, I'm working on other issues too.
I have seen the libSystem, not /system, you'right the /system folder is missing here too.
While I can see the /system in iPhoneOS.sdk 13.5 latest.

 

From this post, it seems to be stubs for iOS, and the real libCache is needed for Macos only.
That Macos folder is still there in my SDK:

Quote

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/lib/system

Maybe not a good idea to use the Macos folder instead, the question would be who needs and links to libCache.

 

Clarifications:
1. From your blog

Quote

/Applications/Xcode/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.SDK
I assume a typo

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.SDK

2. From your last post before

Quote

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneIS.platform/Developer/SDKs/iPhoneOS.sdk/usr/lib/system 
I assume a typo

I need to write more carefully 😉

 

Thanks for your input. I hope to have an answer in the next couple of days or so.

Hi,

 

I like your approach (I'm a heavy user of VMware Fusion myself)

 

With VMware Fusion 11.5.x there's a number of issues when it comes to connecting via USB.

This basically has to do with Fusion's 11.5.x use of kernel extensions.
Make sure that the usb arbitrator is running.

eg.

ps ax | grep "vmware-usb"

should show you vmware-usbarbitrator

If it doesn't then your install is broken and I suggest to download the full installer from https://www.vmware.com/go/downloadfusion drag the current VMware Fusion install to the bin, reboot your host and install VMware Fusion again. The rebooting would make sure that no kernel extensions are still in use.

 

If vmware-usbarbitrator is already running then I might have a suggestion for editing your .vmx file, but let's take it one step at a time.

 

Also note that the next version of VMware Fusion (currently available as a tech preview) uses the native USB stack from Catalina / Big Sur and no longer requires a kernel extension for this feature.

[Rollo62 536]

@wva

Thanks for the hints.

Indeed this command doesn't show the "usbarbritator".

 

But that is missing also in earlier VM's, which is still working perfectly fine with my USB devices.

Anyway, I will try to re-install the VmWare.

 

What I don't get is your note "... download the full installer ...".

When I make a normal update, via the check for updates, do I get a different installer then ?

I've never had seen any difference there.

 

 

 

[Rollo62 536]

@wva

Now re-installed all that, but still no luck.

XCode doesn't recognize my device.

 

The command shows

Quote

username@Rollos-Mac ~ % ps ax | grep "vmware-usb"
  520 s000  S+     0:00.00 grep vmware-usb

which should be OK I guess.

I think that I did this on Windows VM, so I'm not sure how this was before re-install.

Sorry, too many VM's running, and too late in the evening

Anyway, I did the complete clean install.

 

If you have still some tips what to change in the .vmx file, would be great.

Otherwise I have to move to real hardware now, as VM debug is broken.

[Wil van Antwerpen 25]

The usb-arbitrator is a service running at the host, not in a VM.

 

Also make sure you are at the very latest.

The update should be a different installer yes. It wasn't when going from 11.0 to 11.5, but after that it's a different process to update versus the full installer.

Make sure to install 11.5.6 and not an earlier version.

@Rollo62

Hi, i have the same issue in my VM's using Xcode, devices are shown by System Report, but Xcode and Finder can’t see them.

 

Did you find solution for this problem ?

[Rollo62 536]

Not yet working , but I haven't tried again.

Im working on a real Mac Machine right now,

But Ive downloaded VMware 12 already, and will try soon.

 

Sometimes such issues disappear suddenly, I hope...
