I would like to ask you some guidance here.

Once I finished my graduation I join a company for Ruby On Rails. They trained me and put into project for ROR.

I have spent 1 year of ROR development. I have done basic things in the given project. Then my company got a project for QT, learned and worked for nearly 7 months. Then my company put into me in iOS development.

For the past 1 1/2 years, I have been working in the iOS development till date.

Also my main worry is, changing the technology I am working makes me not having in depth knowledge on anything.

I mean I can't make myself as expert in any language. What is your opinion?

Now my company is going to put me into the cross-platform mobile application development. I am worried now, will this affect my growth path by leaving native development? I am ready to learn Android.

As I left web development before 2 year ago, I am finding some odds with me.

Should look for iOS job change now?

Please let me know your advices.
