LooLocator

Find Amenities (like toilets) near you! The simple iOS fetches the crowd-sourced data from OpenStreetMap, and shows toilets within walking distance. User can then use AppleMaps to find walking directions to the amenity.

Design Rationale

The following series of bite-sized posts explain the design rationale behind creating the app:

1. Part 1: Introduction - Writing a modular, and testable iOS App in Swift using MVVM pattern
2. Part 2: Defining the Data Model
3. Part 3: The Location provider
4. Part 4: Defining the networking layer
5. Part 5: The ViewModel
6. Part 6: The Final App - Putting it all together

Getting Started

Here are the steps to get started with the project on your local machine:

1. Clone the git repositiory
2. Run carthage update --platform iOS --cache-builds --no-use-binaries to fetch the dependencies.
3. If running on the simulator, you can edit the scheme and set the simulated location in Xcode. (E.g. Hongkong)
4. Run the project via Xcode.

Prerequisites

What things you need to install the software and how to install them

1. Mac OS X
2. Xcode 9
3. Carthage
4. Optional: xcpretty

Running the tests

The app uses BDD style tests using Quick and Nimble. There are unit tests written to test the LocationManager, APIClient (with Network mocks), and ViewModel behaviors. To run the test, enter the command on the command line.

xcodebuild -scheme 'LooLocator' \
			-sdk iphonesimulator \
			-configuration Debug \
			-destination 'platform=iOS Simulator,name=iPhone 6s,OS=latest' \
			test | xcpretty

The output will be similar to
