Xcode project#
Briefcase supports creating a full Xcode project for a macOS app. This project
can then be used to build an actual app bundle, with the briefcase build
command or directly from Xcode.
By default, apps will be both signed and notarized when they are packaged.
The Xcode project will produce a .app bundle is a distributable artefact.
Alternatively, this .app bundle can be packaged as a .dmg that contains
the .app bundle. The default packaging format is .dmg.
Icon format#
macOS Xcode projects use .png format icons. An application must provide icons of
the following sizes:
16px
32px
64px
128px
256px
512px
1024px
Splash Image format#
macOS Xcode projects do not support splash screens.
Additional options#
The following options can be provided at the command line when packaging macOS apps.
--no-notarize#
Do not submit the application for notarization. By default, apps will be submitted for notarization unless they have been signed with an ad-hoc signing identity.
