Apple should enable Passcode lock for Apps in iOS

I have been using iPhone as my primary mobile phone for several years and the most sought-after feature that would like to have in iOS is the lock/unlock option for Applications. This feature has been in Android for several years and this is one of those missing features in iOS that makes it inferior to Android operating system. There may be several reasons for Apple to not enable this most sought-after feature and I have few reasons on why Apple should enable this feature for its loyal users

• Privacy Protection from friends and family: Even though Apple promotes their superior privacy protection against external forces, it should also enable users to protect their privacy with their close family and friends. The reason being, there would have been time where you had to pass on your mobile phone to friends/family to share stuff and there is high possibility that they might open an application accidentally and it might contain your personal/confidential information. So, in such scenarios Apple’s iOS system lacks feature to lock/unlock an application with passcode authentication to protect against accidental access from your friends or family. 
• Protect Kids from unauthorized access: Another reason on why Apple’s iOS system should enable application lock/unlock feature is accidental access by Kids and protecting critical office application access to children. With evolution next gen kids accessing mobile or iPad devices for games and videos, there are high chances that they might click on your critical office application or your personal projects with confidential information and accidental deletion of files. So, in such scenarios there should have been option to lock/unlock option with passcode for applications and it also helps in restricting kids access to video apps or games only to certain limits.
