The following two lines work in Mojave, but flag an error in Catalina: >>> from AppKit import NSSavePanel >>> panel = NSSavePanel.savePanel() The error is: 2019-10-29 18:24:22.275 Python[6577:255233] *** Assertion failure in +[NSServiceViewController currentAppIsViewService], /BuildRoot/Library/Caches/com.apple.xbs/Sources/ViewBridge/ViewBridge-462/NSViewService.m:140 2019-10-29 18:24:22.275 Python[6577:255233] *** Assertion failure in +[NSServiceViewController currentAppIsViewService], /BuildRoot/Library/Caches/com.apple.xbs/Sources/ViewBridge/ViewBridge-462/NSViewService.m:140 2019-10-29 18:24:22.342 Python[6577:255347] +[NSXPCSharedListener endpointForReply:withListenerName:]: an error occurred while attempting to obtain endpoint for listener 'com.apple.view-bridge': Connection interrupted This is with PyObjC 5.2. I get the same error (or not) in python 2.7 and python 3.7.

ANN: PyObjC 6.0
by Ronald Oussoren Oct. 17, 2019

Oct. 17, 2019

I've uploaded PyObjC 6.0 to PyPI. This is a major feature release, the two most important changes are the addition of support for frameworks and APIs introduced in macOS 10.15 (Catalina), and the removal of support for Python 2.7. PyPI has wheels for 64-bit builds of Python 3.6, 3.7 and 3.8. The source should still work with 32-bit builds of Python, but those are no longer tested. At the time of writing the source code is still in the branch "pyobjc-6-branch". The full list of changes: * Removed Python 2 support from the C extension in pyobjc-core * Reformatted code in pyobjc-core: - Use "black" for Python code - Use "clang-format" for Objective-C code As a side-effect of this all usage of "NS_DURING" and "PyObjC_DURING" has been replaced by the expansion of those macros, mostly because "clang-format" doesn't understand these kinds of blocks. Replacing PyObjC_DURING by its expansion also reduces the knowledge needed to understand what's going on w.r.t. the Python GIL. The macro PyObjC_DURING, and its siblings, have been removed as well. * Updated bindings for macOS 10.15 (Xcode 11.0) * The userspace driver frameworks introduced in macOS 10.15 (DriverKit and related frameworks) will not be exposed through PyObjC. Please let me know if you have a good use case for using these frameworks with Python. * Add new framework wrappers for all other new frameworks in macOS 10.15: - AuthenticationServices - CoreHaptics - CoreMotion - DeviceCheck - ExecutionPolicy - FileProvider - FileProviderUI - LinkPresentation - OSLog - PencilKit - PushKit - QuickLookThumbnailing - Speech - SoundAnalysis - SystemExtensions * Add new framework wrappers for a number of older frameworks: - MetalKit (new in macOS 10.11) * Issue #271: Fix crash when creating NSData objects on macOS 10.15 P.S. This release is later than I'd like for various reasons, but mostly because I've spent less time at my computer the last couple of weeks. — Twitter: @ronaldoussoren Blog: https://blog.ronaldoussoren.net/

Looking for PyObjC and py2app users
by Ronald Oussoren July 19, 2019

July 19, 2019

Hi, I’m looking for users and usages of PyObjC and py2app for a number of reasons. - I’m personally interested in what people are doing with my projects, this not just strokes my ego but also tends to show fun usecases - I’d like to add information to the documentation on how and why PyObjC is used - I’d like to add links to (OSS) projects to the documentation, amongst others as more realistic examples than the example code in the repository - Links to source code can help me improve PyObjC For py2app I have similar reasons for being interested, but there’s another one: py2app is getting long in the tooth and requires tweaking for a lot of programs using it. Finding examples of such tweaks helps me improve py2app, and can also help in creating an integration testsuite for py2app. Feel free to contact me directly.

PyCon 2019
by Jeremy Reichman April 16, 2019

April 16, 2019

I got approval to attend PyCon 2019 this year but found it was sold out. I’m severely bummed by this. Does anyone know if there is a wait list? Or have a promo code available? I can only attend May 1-5, anyway, but I’m really sad to miss what would have been my first PyCon. -- Jeremy Reichman jaharmi(a)jaharmi.com

[ANN] modulegraph2 2.0a1
by Ronald Oussoren Feb. 2, 2019

Feb. 2, 2019

Hi, I’m happy to announce a new library: modulegraph2 version 2.0a1. Modulegraph2 is a complete rewrite of the modulegraph library that powers py2app and will end up in py2app in the future. The new library is python 3 only and has proper test coverage. This should make it a lot easier to evolve the library in the future. A longer write-up is at my blog: https://blog.ronaldoussoren.net/2019/02/03/modulegraph-a-python.html <https://blog.ronaldoussoren.net/2019/02/03/modulegraph-a-python.html> Ronald — Twitter: @ronaldoussoren Blog: https://blog.ronaldoussoren.net/

PMPrinterPrintWithProvider
by Ben Byram-Wigfield Jan. 28, 2019

Jan. 28, 2019

Hello I want to use some of the Printing APIs, but I’m having trouble finding them. Have things like PMPrinterPrintWithProvider, PMPrinterPrintWithFile, been implemented in PyObjC? I can’t find them in ApplicationServices, AppKit, Quartz or CoreFoundation modules. Thanks Ben

[ANN] PyObjC 5.1.2
by Ronald Oussoren Dec. 14, 2018

Dec. 14, 2018

Hi, I’ve pushed PyObjC 5.1.2 to PyPI. This release contains a number of bugfixes: * #254: Fix compile error on macOS 10.9 or earlier * #255: Calling completion handler failed due to incomplete runtime info PyObjC's metadata system didn't automaticly set the call signature for blocks passed into a method implemented in Python. This causes problems when the ObjC or Swift block does not have signature information in the ObjC/blocks runtime. * Use MAP_JIT when allocating memory for the executable stubs for Python methods. With the "restricted" runtime you'll have to add the "com.apple.security.cs.allow-jit" entitlement to use this flag, in earlier versions you'd have to use a different entitlement: "com.apple.security.cs.allow-unsigned-executable-memory". The MAP_JIT flag is only used on macOS 10.14 or later. * Ensure that PyObjC can be built using /usr/bin/python on macOS 10.14 This failed due the problems with header files in the SDK included with Xcode 10.

Hi, I’ve pushed PyObjC 5.1.1 to PyPI. This is a very minor feature update: it adds a small number of symbols introduced in the macOS 10.14.1 SDK included with Xcode 10.1. Ronald
