Swift Type Inference Benchmarks

Whenever you want to use these benchmarks in original or modified form, you need to mention the original author (me, Lucas van Dongen) and link back to this repository.

A set of benchmarks that compares various aspects of type inference affecting compiler performance. Here are the results when ran on my machine (a 16" 2019 2,3 GHz 8-Core Intel Core i9 MacBook Pro). If you want to run the results for yourself skip towards the set up section

Strings and Numbers

Arrays

Dictionaries

Constructables

Computed Container

How to set up the benchmarks

First set up all of tools necessary to run the benchmarks:

Install at least one version of Xcode
Install Hyperfine
Install Python 3

How to run the benchmarks

Run python3 file_test.py in the Terminal from the SwiftBenchmarks folder.

Warning: BareComputedContainer can run very slow on your computer. If want to exluded it just edit file_test.py in any text editor and excluded it as follows:

    ...
    'LargeTypedMixedArray': ['LargeTypedMixedArray.swift'],
    'LargeInitMixedArray': ['LargeInitMixedArray.swift'],
    'TypedComputedContainer': ['BookingData.swift', 'TypedComputedContainer.swift'],
   # 'BareComputedContainer': ['BookingData.swift', 'BareComputedContainer.swift']#,
    'FunctionBareInit': ['FunctionData.swift', 'FunctionBareInit.swift'],
    'FunctionTypedInit': ['FunctionData.swift', 'FunctionTypedInit.swift']
}
