How to fix Thread 1: signal SIGABRT

I'm creating an app to control tv buttons. My code is working with light, but not TV (IR transmitter).

2019-10-25 22:23:53.259608-0400 jpackHomeAutomation[5455:274138] [Graphics] UIColor created with component values far outside the expected range. Set a breakpoint on UIColorBreakForOutOfRangeColorComponents to debug. This message will only be logged once.
Over Head Light is On.
Over Head Light is Off.

You probably want the “Using Swift” section of the forums; this section is about development of the language itself.

jpackHomeAutomation[5455:274138] -[UIButton loadRequest:]: unrecognized selector sent to instance 0x7ff7147607c0

This error message (which is a holdover from Objective-C, hence the odd wording) means that you tried to call a method named loadRequest(_:) on a UIButton, which doesn’t have such a method. Judging from the name, perhaps you are trying to make the button’s action be a method on the controller, but you accidentally set it to call that method on the button instead. Check any addTarget(_:action:for:) method calls and Interface Builder/Storyboard connections related to this and see if they’re hooked up to the wrong target.
