What's the minimum required Xcode version? #30

Closed mathielo closed 4 months ago

From the docs:

OSX: uses Cocoa's NSAlert/NSSavePanel/NSOpenPanel classes

Checking their docs, NSAlert / NSSavePanel / NSOpenPanel requires the macOS SDK 10.3+.

We're tried to build a project using dialog in a fairly old Mac with Xcode 7.2.1, which supports macOS SDK 10.11.2, but we got these errors:

We tried in a different mac with Xcode 9.1 and it worked without any issues. Didn't try with Xcode 8, not sure whether it works with it.

Anyway, the point is: what is the actual minimum supported Xcode version - and perhaps it could be added to the docs by the required Cocoa's classes? I know most people are always on latest versions, but every now and then someone needs to run stuff in older machines and it's nice to know the exact requirements. :bulb:

Good question! Thanks for sharing your findings here; I don't even have a real mac to test on, nor spare time to test with ;)

81 introduced the use of NSApplicationActivationPolicyAccessory which requires macOS 10.6+; I've updated the README to reflect this.
