この関数を使用してタイムスタンプを生成しています。ここスタックオーバーフローのどこかで見つけました。
@objc public class var timestamp: String {
return "\(Int(NSDate().timeIntervalSince1970 * 1000))"
}
問題なく動作していますが、EXC_BAD_INSTRUCTION:
fatal error: floating point value cannot be converted to Int because it is greater than Int.max
このアプリの開発が完了に近づいているため、突然 EXC_BAD_INSTRUCTION が発生するのを見て緊張します。これはシミュレーターで実行されていますが、有効な日付と時刻が設定されています。
任意のアイデアや提案、または大歓迎です。以下はバックトレースです。
