XCTAssert(value > 10, "value not greater than 10", file: file, line: line)
XCTAssert(value < 20, "value not less than 20", file: file, line: line)

abbeyjackson / Translate touches to underneath view
Last active May 18, 2017 19:05
When you need to translate touches to views through other views you can use the hitTest method on the CONTAINING view. The hierarchy that this applies to is included as well.
class ContainerVC: BaseViewController {
override func loadView() {
view = ContainerView()
}
func addButton() {
// add the button
}
}

Last active July 21, 2016 21:18
Add $ or anything else to beginning of UITextField. The following will prepend a $ when the user types in a textfield and have it deleted when the user deletes their last character
func setUpPriceTextField() {
priceTextField.delegate = self
priceTextField.addTarget(self, action: #selector(textFieldDidChange), forControlEvents: .EditingChanged)
}
// MARK: UITextFieldDelegate
func textFieldDidBeginEditing(textField: UITextField) {

Created May 5, 2016 19:32
iterate through an enum. Not possible but can fake it like this. If you conform to ForwardIndexType you can also use methods like advancedBy and distanceTo
enum Number: String, ForwardIndexType {
case One
case Two
case Three
case Four
case EndIndex
func successor() -> Number
{
switch self {
