so good morning everyone my name is
Joseph be introducing our work we have
done for the eternal foundation sorry a
little bit about my voice after all
these amazing events and parties I'm a
little bit a little bit sick but I'm
enjoying the conference so briefly who
we are we are called aqui some some of
you guys think that we are we are
startup so that's why I always present
it a little bit we are we are basically
a storehouse here from Prague and we
develop mobile apps this is what we what
we do for a living we also have offices
in Berlin and we are quite quite big
nowadays we 450 members and usually we
develop mobile apps but blockchain for
us is basically another type of a
back-end so so that's why we came to
contact with with it and then we really
like some tools that we could use in
order to deliver mobile apps as we are
as we are used to so that's how this
project came up our usual projects are
something like this now we are working
on mobile app for German parliament
which will be launched in about month
not lately we have been working on a lot
of projects in blockchain and I believe
blockchain is one big quartz so there's
no competition between each other so the
same thing we do for a Tyrian foundation
we do also for Commons Foundation we are
helping them to deliver the developer
tools they would need to complete their
ecosystem and we also have one funny app
that we have created during a hackathon
and it's a quite typical use case
because as I was here at Monday the
other plasma talks never as a use case
also rock-paper-scissors at so it's like
typical blockchain app all relate is
that we we have created some kind of app
where you can bet king tokens which is
summer and a recurrence ironic partly on
the theorem parts
and this is going to to get to Android
store in about two weeks but I guess you
are here because of this which is the
project that we get a grant for a Tyrian
Foundation and it's basically a set of
tools or defecate to allow smooth
development on iOS so what is it it or
maybe before I begin question could you
raise your hands who refuse developer
right and blockchain developers okay so
these two groups sometimes overlap as
I've seen but most commonly use case is
that they don't over it
so basically when there is a start-up or
or company that wants to develop a
mobile app that works with it even
blockchain they they have iOS developers
who never evolve a blockchain and for
them parsing the free jeaious interface
is just nightmare and understanding how
the smart contracts work is basically
they don't want to do it and it's it's
reasonable that's not like their their
typical work on the other side
blockchain developers they don't know
how to create iOS mobile apps so this is
for me something like motivation to
create a defecate which will which will
help both sides to be able to work on
this technology so what does it consist
of there are basically three sub
projects that it relies on and the first
one is something we call mvvm project
template I will introduce it in another
slide then there are low level
communication libraries and there's a
code gen which is the most interesting
part I guess so the first part this is
something that when we had talks with 18
foundation they were really excited
about it so we made it a part of the
difficut but it's not it's not a
mandatory to use basically as I told we
are an agency that develops my labs
which means we start a new at project
about every month and for this reason we
have internally created some kind of
project skeleton template which helps us
to
start projects really quickly because
most of the mobile apps have something
in common and what do they have in
common in our case is the architecture
we are big fans of model view viewmodel
architecture and this skeleton we have
made it an open source so it's open
source done on our github you can see
the link down there and one of the one
of the key key things is that we don't
really like storyboards so this helps us
to define the flow between single single
views as a code and also there are small
things like switching between single
environments I mean like stage
production and so on so this is all
handled by the by the project template I
will say that we are not saying that
this is the right way how to develop iOS
apps but this is the way that works for
us and you are more welcome to try to
use it as well the motivation I can set
in our case is that we are able to start
a new projects really quickly and our
board for example new programmers to our
tech stack very quickly as well so it's
been it's been open sourced and you can
you can try it the second part of the
difficut is something we call all our
communication libraries and this is
usually the Deaf kid and we didn't do
this part because that was done by
another grantee circuit we just
correlated with them our work and it was
I think a very good cooperation so
basically we built on this tool what
does this this tool or library what does
it do it does all the stuff like
handling transactions so you don't have
to parse the web 3GS manually and things
like this
it has a wallet in it so this is like
the basics you need in your iOS app in
order to communicate with the blockchain
so we go at low-level tools and what
we've done next is that we have created
a code generator as we call it and this
part basically has an input
API of children smart contract and as as
output there are cons swift code out of
it so it's basically generator of sweet
swift code with this approach
programmers can natively call the
functions of the Smurfs contracts from
Swift and the calls are type safe and it
also has all the covers our educators
like parsing different each hiriam types
to swift types so basically from the
developer point of view it's something
like an SDK and this SDK is created
custom for each smart contract which
means in this case if your project has I
don't know in your team you have Al's
developers and you provide them with a
link on this on this this house difficut
then they basically just run it over the
existing smart contract and as an output
they have all the source code they need
to communicate with the smart contracts
so they the the ice developers in that
case don't really need to deeply
understand understand the blockchain a
and they're also don't need to do the
annoying voice work with parsing or all
the low level stuff because this this
code gen has of course included s
independence a the eat irrigate and our
MV and template is not an dependency but
you can use it with that or you don't
have to use it with that it's it's up to
it's up to you so here down is the link
on our github of this or this kit it's
it's been published last week but of
course feel free to to open any issues
or discuss with us anything that that
you would like we still plan to of
course support it what's the result of
of this work yesterday we had a small
hands-on workshop in our office where we
demonstrated that we are able to create
a new native swift iOS app that calls
functions in smart contracts under 30
minutes
so it's like really quick start and we
also on the github but there's an
installation guide and we've also
written a blog post where you can see a
real step-by-step guide how to create
yep this is more for for example for the
blockchain developers if you are not
familiar if Isles so with this with this
blog post you are able to build the
native app really in the certain minutes
if you if you don't have any any more
other other other background so these
are I think the promising results that
we that we have and yeah you are more
than welcome to to use it and if you had
any questions I have with me my
colleague Mark who's been working on the
projects as a developer so we can either
I know who your time discuss it here on
stage or then off stages we will be
hanging out here for a while as well so
thank you
you
