Development of Native iOS SDK based on current React Native SDK
We currently have an SDK for our mobile wallet application developed using React Native (written in Java Script), we are internally developing a Native Android (Java) version and seek to find an external developer to create a Nation iOS implementation. The SDK contains functionality to communicate securely with our servers, and interact via the NFC interface with an external device. We seek the development of the Nation iOS implementation based on the React Native version which already works on Apple (iOS) phones. This SDK is then used to build commercial applications such as: https://apps.apple.com/pl/app/manage-mii/id6446908503 At this stage we are seeking to identify companies who can complete this task, and can show previous experience with using NFC on an iOS device. Ideally UK companies are preferred, however we are open to companies based anywhere in the world provided all communication (written and verbal) can be conducted in English. More details can be shared directly to allow us to identity potential companies able to complete this project, however full details will only be shared once we have shortlisted a few companies and NDA's are in place. Strictly no agencies, we are seeking to engage the developer (or small development company) directly.
