Value of type '(CGRect) -> CGRect' has no member：是由于你变量类型定义错了

Value of type '(CGRect) -> CGRect' has no member 'maxY'
Value of type '(CGRect) -> CGRect' has no member 'maxX'
Value of type '(CGRect) -> CGRect' has no member 'width'
Value of type '(CGRect) -> CGRect' has no member 'height'
Value of type '(CGRect) -> CGRect' has no member 'size'

是由于你定义的某个变量属性不对，多半应该是 CGFloat，而你没有规定变量类型，系统默认识别成了 Int 或者 Double 类型swift

let frameWidth = 300 // 识别为 Int

// 改成
let frameWidth: CGFloat = 300
