    The iPhone app development company is always looking for certain specifications for hiring iPhone app developer. The company would hire the iOS app developers on the basis of the qualifications that they have.

    The iPhone app developers are mostly qualified as junior, mid-level, and other senior developers. The differences between these developers are on the basis of experience, technical knowledge, and the roles that they have.

    Junior, Mid-level, Senior iOS App Developer Roles

    Junior iOS App Developer

    A junior iPhone app developer is an intern and has about 8-10 months of working experience in total. They have a basic knowledge of iOS application development companies and hardware along with software options.

    Also, these developers have little knowledge about programming and coding as well. They report to the mid-level iOS developers for the tasks allotted to them.

    Their job is to assist the mid-level developers in the projects and handle some small tasks associated with the projects to minimize the risk. Since they are not directly on the projects; there are not many tools that can be used by these developers.

    Mid-Level iOS App Developer

    Mid-level iOS developers have about 1 and a half or about 2 years of experience and they are the ones that handle the small and insignificant issues that happen in the iOS systems.

    So, these developers need to have little knowledge about the internal features and the tools. Tasks related to programming languages are handled by them at a certain level.

    A mid-level developer reports to the senior developer for the projects. Their job is to assist senior developers, complete the section of the project and handle the junior developer.

    The Mid-Level developers handle about 30% of the project work when it comes to iOS app development.

    Senior iOS App Developer

    A senior iOS developer is a person that has work experience of about 2-3 years. Also, a basic knowledge of the programming languages such as C++ is essential for senior developers. They also need to have experience in handling software problems and issues.

    The senior iOS developers would be reporting to the Guru developers in the projects and they handle about 50% of the work.

    Guru iOS App Developer

    Another one of the most experienced and important categories of iOS developers is the Guru developers. They have work experience of about 5 years in total. The tasks which are assigned to the Senior and Mid-level developers are decided by the Guru iOS developer.

    The Guru developer reports to the Ninja Developers during the project. They handle about 50-60% of the work in any project.

    They are masters in programming languages and coding. Hence, they have knowledge about other technologies as well. Almost every section of the project can be handled very easily by a ninja developer.

    Apart from that, the Ninja developers assign the projects and the tasks to the Guru and Senior developers. They don’t have to report to anyone as they have the highest position.
