Over a call, the developer’s ability to communicate in an articulate manner is tested. A deeper understanding of the candidate’s technical experience and also motivation to freelance is achieved.
Over one or more F2F interviews, the developer’s involvement and performance in building complex software products are assessed. This sets the platform to delve deeper into technology-specific discussions.
Developers' mental agility and problem-solving abilities are tested through a coding test involving algorithmic as well as skill-specific problems. A mixture of live evaluation and timed coding tests is used.
The live experience of working with developers is verified by reaching out to past clients and/or employers. Inputs on various qualitative factors such as reliability, punctuality, communication and responsiveness are received.
Performance during each engagement is continually assessed. Our developers are expected to maintain Flexiple standards across all engagements with our customers.
Swift is a general-purpose, open-source programming language developed by Apple in 2014. It is mainly used for native iOS and macOS development. Swift is a powerful and intuitive language that can be picked up by developers easily. Apple developed the Swift language that was suited for fast-paced app development and to also counteract some of Objective-C’s disadvantages.
If you’re looking to hire a freelance Swift developer for your company, this guide is going to help you find the perfect fit. We’ve included everything you need to know about hiring a freelance Swift developer.
We have broken the sections into the following parts:

The following are some of the tools used by Swift developers at various stages of development:

Below are some key points that we at Flexiple have learned through trial and error - a process of filtering through over 15,000 developers.
Now that you have made a quality JD, it can still be tricky to evaluate the skills of your applicants. To help you with that, we have created a pool of questions that a good software developer should be comfortable with.
It is important to note that the ability to answer these questions doesn't imply that you have a top quality candidate. But it definitely is a big step in that direction.
To help you navigate through these questions, we’ve categorized the interview questions in 3 parts:
A. Basic concepts: Includes all basic concepts used across languages but we've focused on their significance in Swift. This will give you an understanding of how strong their programming foundation is.
B. Advanced concepts: Includes all concepts that someone with higher expertise should know.
C. DS/Algorithm questions: To test the logical capability of the candidate.
class ValidParenthesesFunc { func isValid(_ s: String) -> Bool { var stc = [Character]() for char in s { if char == "(" || char == "[" || char == "{" { stc.append(char) } else if char == ")" { guard stc.count != 0 && stc.removeLast() == "(" else { return false } } else if char == "]" { guard stc.count != 0 && stc.removeLast() == "[" else { return false } } else if char == "}" { guard stc.count != 0 && stc.removeLast() == "{" else { return false } } } return stc.isEmpty } }
The above code will input 0(false).
$x = 10; $y = 5; $z = 3; if ($x / $y / $z) print "hi"; else print "hello";
The answer is A because the floating-point division returns a non zero value = 0.66 which evaluates to true and outputs ‘hi’.
$x = 2 $y = 4 $z = 6 if($z > $y > $x) { echo “true”; }else{ echo “false”; }
The answer is False. It may look like the output can be true because 6 > 4 > 2 is true, but PHP evaluates $z > $y first, which returns a boolean value of 1 or true. This value (true or 1) is compared to the next integer in the chain, bool(1) > $z, which will result in NULL and echo “false.”
As discussed, it isn't easy to find a quality freelance software developer but this guide makes the process easier for you. To offload the entire hiring process, reach out to us at Flexiple. We've designed a high-quality, 6-step screening process to find the top 1%, freelance developers. You can find the best freelance Swift developers here.

Lastly, to quickly summarize it for you:
1. Note your project requirements and hire accordingly. Do not go for the lowest or the highest-paid developer.
2. Don’t hire without vetting- consider asking questions right from the basics to advanced to logical questions.
3. Look for companies like Flexiple that help you find the perfect fit.
That is everything you need to know about hiring a freelance Swift developer. Happy hiring! :)
