• When creating production-ready screenshots (AppStore, landing pages, etc) it's a nice detail to do it the "Apple way"
• That means 9:41 time, full signal, full wifi and full battery .. curious why?

xcrun simctl

• Since Xcode 11 it's possible to modify these values directly in the Simulator via xcrun simctl - find more here
• However this feature has stoped working in Xcode 14.1 and is still broken (Xcode 15.2 at the time of writing this)

SimulatorStatusMagic

• Download SimulatorStatusMagic and run build_and_inject.sh booted - look into docs for more info
• If you need to modify some values you have to change it in SDStatusBarManager/SDStatusBarOverriderPost[iOS-version].m
• For example if you don't want to show battery percentage change ProminentlyShowBatteryDetailStatusBarItem to NO

Photoshop

• Of course you can always just Photoshop the values, this is easy when the background is a simple color, it gets complicated for gradients/photos/etc
• You can find default status bar in the Apple Design Resources
• Two simple templates for iPhone 15 screenshots (1179x2556) are available below
