Is there a way to use if let on an array. If the array has a value at index let it equal this value.
if let view = self.view.subviews({$0.tag == 1 })[0] {
view.backgroundColor = UIColor.blackColor()
} else {
print("No view with tag 1")
}
You can use the filter functionality, and use first instead of [0], to avoid crashes if the filtered array has no elements:
if let view = self.view.subviews.filter{ $0.tag == 1 }.first {
Swift 3 added the Sequence.first(where:) method, which can replace the calls to filter and first in Cristik's answer.
The advantages of first(where:) over filter { ... }.first are (a) the code becomes marginally clearer and (b) more importantly, better performance when the array is large or the closure is expensive because it stops after finding the first match.
if let view = self.view.subviews.first { $0.tag == 1 } {
...
}
