Change default global tint color in swift

Question

I'm developing a little app and I would like to change the default global tint color from blue to orange. I've seen many ways to do it in Objective-C but I can't seem to get it to work using swift. How could I achieve this? Thanks in advance!

Answer 1

A small update from Apple here. Tested with Xcode Version 12.4.

There is now an AccentColor in the Color Asset catalogue which can be set in the build settings. In newer projects it is set by default but older projects might need to add it manually.

1. Create a Color Asset with the name "AccentColor" (or whatever you like)
2. Go to your Build Settings of your Target and add the name of your color asset as the value for the entry "Global Accent Color Name".

Note that AccentColor asset-name is NOT a preserved keyword, and can be anything custom, but the Build setting is what makes this work.

Basically, iOS has nothing equal to the Android theme yet (2021), where standard colors have keywords, and we can not simply set those in assets.

This answer was last revised for Swift 5.2 and iOS 13.5 SDK.

You can set the tintColor on your window. Because tint color cascades down to all subviews (unless explicitly overridden), setting it on a window will effectively make it global inside that window.

Add the following line to your application(_:didFinishLaunchingWithOptions:) or scene(_:willConnectTo:options:) just before making the window key and visible:

window.tintColor = .systemOrange /* or .orange on iOS < 13 */

You can also set in in the storyboard by changing the Global Tint property:
